Environmental Public Health Tracking: Topics and Public Data

The Tracking Program is excited to introduce our new public data portal!  The new portal, launched in November 2015, is more efficient and user-friendly, with improved mapping, exporting, and mobility. The most critical upgrade is the integration of sub-county level data, such as those at the census tract level. 

We are moving data topics over to the new portal gradually. Currently, data on air quality (ozone and PM2.5), heart attack, asthma, cancer, and lead poisoning are on the new portal. All other data topics are on the old portal but will be moved over soon. To be notified when data are added to the new portal, sign up for our newsletter

Users having trouble accessing the portal should skim Portal Troubleshooting (PDF, 229 KB).  If that doesn't work, try updating your web browser (for example, Firefox) to the most recent version.  If you are still having trouble, please contact Tracking staff.


The Tracking Program hosts data on nearly a dozen environmental public health topics.  Select your area of interest to learn more and to access the data portal.


The Tracking Program has access to data via the Wisconsin Poison Center.  Learn more on our secure data page.
